The sky over Rajpath on Saturday lit up in a kaleidoscope of colours as a swarm of 1,000 drones painted 3-D images of Bapu with his walking stick, the tricolour and the map of India. The brain behind the event were two IIT-Delhi alumni and their professor who spent six months to design and manufacture the drones and prepare different animations to be recreated in the sky.
Tanmay Bunkar and Anuj Kumar Barnwal, physics graduates from IIT Delhi, co-founded their startup Botlab Dynamics along with Dr Sarita Ahlawat in 2016. Their aim was to replace big, expensive drones with simpler and cheaper drones that can perform the same tasks and carry the same payloads by forming a network or collaborative aerial system. Over time they received funding from the Department of Science and Technology and I-Hub Foundation for Cobotics (IHFC)at IIT-Delhi.
